SIDE FRAME.

Application flied May 28, 1925, Serial No. 83,482. Renewed August 20,1828.

This invention relates to side frames for railway car trucks, and moreparticularly to such frames formed from sheet metal blanks.

One of the principal objects of my inven- .tion, generally considered,is the formation of wrou 'ht metal side frames formed with means forsupporting the bolster springs whereby it is possible to eliminate theuse of a spring plank as well as other improved features.

An object of my invention is the provision of a pressed metal truck sideframe formed from a blank of sheet metal folded upon itself and unitedalong ortions of its lower edge and at other portions by rivets or thelike, said frame comprising compression, tension and bolster columnportions and provided with a member resting on the upperportion of thetension member and connected to the bolster column portions for thepur-.

pose of supporting the bolster springs.

Another object of my invention is the provision of a frame for railwaycar trucks formed with compression, tension and bolster column portions,said portions being so spaced that a window opening for the reception'ofthe bolster is provided the lower portion of said window opening beingpartially enclosed by a spring pan connected to adjacent portions of thebolster columns and extending t-h'erebetween whereby the necessity of aspring plank is obviated.

A further object of my invention is the' provision of a sheet metal sideframe formed with compression, tension and bolster column portions, thelower'portions of the bolster columns being connected by plates, whichplates are extended or bulged outwardly to form supports for embracingthe bolster springs, the lower edgesof said plates being formed withinwardly extending flanges ada ted to underlie the bolster springs andpreferably provided with spring positioning bosses thereon. v

A still further object of my invention is the provision of spring pansconnected to the bolster column portions of railway car trucks providedwith flanges supported on the tension members of said trucks andunderlying the bolster springs and upward extensions along the bolstercolumns forming bolster guide portions.

An additional object of my invention is ment of aflange or flanges onthe journal box and cooperating abutting portions on the, frame, saidcooperating portions being preferably riveted together or otherwisesuit-. abl connected.

ther objects and advantages of the invention relating to the specificdetails of construction and arrangement of parts will become apparent asthe description proceeds. Referring to the drawings illustrating myinvention, the scope whereof is defined by the claims:

Figures 12 and 13 are transverse sectional views on the correspondinglynumbered lines of Figure 8 looking in the directions of the Referring tothe drawings in which similar reference characters designate like partsin the several views and considering first the embodiment of myinvent-ion illustrated in Figures 1 to 7 inclusive, there is shown aside frame 1 constructed from a single sheet of metal by bending a blankthereof to form a plurality of compression member of the diagonalportions 8 of the tension titl till

member 3 are preferably secured together by rivets 9 or other suitablesecuring means.

A preferred construction of the compression and tension members is toprovide 1nwardly extending flanges thereon so that said members aresubstantially box shape in section as illustrated particularly inFigures 3 to 7 inclusive.

The inwardly extending flanges on the diagonal portions 3 of the tensionmember are referabl continued as downward extensions 10a utting along acentral longitudinal plane and the connecting rivets 9 passtherethrough.

The bolster column or strut members 4, in the present instance, areformed as upright extensions from the upper flanges on the tensionmembers and the downward flanges on the compression portions, saidbolster col umn or strut portions being preferably connected by rivetsll.

The intermediate or substantially horizontal portionlQ of the tensionmember 3 is adapted to receive spring seating pans or plates 13, one panextending on the outer and one on the inner side of the frame, asillustrated particularly in Figure 2, for holding the bolster springs inoperative positions. Said plates 13, in the present instance, compriseupright portions 14: extending between and connected to the bolstercolumn portions 4t by a plurality of rivets 15, said rivets also servingas additional connecting means between the portions of the bolstercolumns.

In the present instance the ends of the upright portions 14 of thespring-pans 13 are extended upwardly at 13 along the bolster columnportions and formed with outwardly extending flanges 17 serving asbolster guides. The extensions 16 are also preferably connected to thebolster column portions by rivets 18. y

The spring pans 13 are preferably provided with substantiallyhorizontal. flange portions 19 resting on the upper flanges of thetension portions 3 of the side frame and preferably formed with springbosses 20 for properly positioning the bolster springs (not shown). Theupright portions 14: of the spring pans are preferably curved or nvoaeeabulged outwardly so as to accommodate the bolster springs and yet snuglyembrace them said springs at their inner sides being held in position byupward extensions 21 from the upper inwardly extending flanges on thetension portions 3. Said flanges or extensions 21 are preferably unitedby a plurahty of rivet means 22. At each end on the side frame there isconnected a journal box 23, said journal box being preferably formedwith flange portions 24 embracing the ends of the side frame andconnected to the sides thereof by a plurality of rivets 25.

The flanges 24: on the journal boxes are preferably ofl'set belowthediagonal portions 8 of the tension members 3 so as to closely embracethe extensions 10 from the flanges thereof and areconnected thereto by aplurality of rivets 26.

From a consideration of Figures 1, 2, 4

and 5 particularly, it will be apparent that 1 the journal boxes arevery rigidly secured to the ends of the side frame as the flanges onsaid journal boxes are formed to snugly t against the sides andextensions from the side frame and the top or roofof the journal boxsnugly fits against the outer portions of the lower flanges on the endsof the side frame. I

By virtue of the spring pan construction under the window opening 5provision is made for snugly holding the bolster springs in operativepositions, said springs being supported in position around the springbosses 20 and held against tipping by the upright portions It of thespring pans and ghe extensions 21 from the tension memers 3.

Referring now to the embodiment of my i column portions are formed bymerely slightly oflsetting eontinuations of the side walls of thecompression and tension members. All of said frame members are formedwith inwardly extendingflanges. as in the first embodiment, the loweredges of the diagonal portions 8 of the tension members are connectedtogether by rivets 9 extending through extensions 10 from the inwardlyextending flanges on the tension portions 8.

As in the previous embodiment, 5 ring pan members or plates 213 areprovide upright portions 14 thereof extending between and portions 19are riveted at their ends to the bolster column portions 4, asillustrated, the rivet means being designated by the reference character15. In the present instance the sprin pan members 13 are not continuedupward form bolster guide portions as the bolster columns being ofrectangular or box section are of substantially the proper size for thatpurpose. It is preferable, however, to provide said bolster columns 4with wear plates 17*.serving as bolster guides, said wear plates beingsuitably connected to the bolster columns 4 by rivet means 18 or thelike.

As in the first embodiment of my invention, the spring pans 13 areprovided with inwardly extendin flange portions 19 resting on the upperanges of the tension portions 8- and adapted to underlie and support thebolster springs (not shown). Said flange referably provided with springbosses 20 or properly centering the springs.

In the present instance, the inner edges 28 of the flange portions 19are curved, as illustrated particularly in Figures 9 and 11, to

conform with the upwardly extending portions 21 from the tensionportions 3 which,

in the present instance, are not continued substantially vertically fromthe inwardly extending flanges on the upper edge of the tension portionsbutare curved gradually from said flanges upwardly and inwardly.

and are also curved transversely, as illustrated particularly in Figure11, to more closely embrace the bolster springs and provide separatingembossed portions 29 therebetween. i

As in the previous embodiment, the extensions 21 between bolster springsare connected together by a plurality of rivet means 22. At the ends ofthe frame there are connected journal boxes 23, said journal boxes beingillustrated as of somewhat different construction from those of thefirst modification, that is, they are each provided with an inwardlyextending lug 24 which is cmbraced between and riveted to the extensions10" from the diagonal portions 8" of the tension members 3. The rivetmeans for this purpose is designated as 26.

The top or roof of each journal box in-' stead of being connected to theframe by flanges from the journal box is connected thereto by a channelor U-shaped member 30 which rests on the inwardly extending flanges atthe lower portions of the ends of the side frame and is connected tosaid flanges and to the roof of the corresponding journal box by uprightrivet-s 31. The arms or upwardly extending flanges 32 from the channelshaped, connecting member 30 are secured to the side Walls of the frameat the ends thereof by a plurality of rivets 33 or other suitableconnecting means, as illustrated. In this way the journal boxes are lyto the elaborate flange construction illustrated I in the firstembodiment.

In view of the aforcdescribcd construction, it will be apparent that Ihave provided means for supporting the bolster springs so that the useof a spring plank of any kind may be dispensed with. Inasmuch as thelower portion of the window or bolster opening has been partially closedby the spring pans, the bolsters used withsuch side frames will be madewith removable outside guide lugs in order to enter the window opening.

The two halves of the side frame, as will be apparent, are very rigidlysecured together not only by the rivets 9 and 9 connecting the lowerportions of the diagonal tension members but also by the rivets 22 and22 connecting the extensions from the upper portions of the tensionmembers. The rivets l1 and 15 in the first embodiment also serve forconnecting the portions of the frame together. In this way a very rigidconstruction is secured.
